Zusammenfassung
1. Bei größerer interindividueller Schwankung zeigt die Ausscheidung von β-AIB im Urin eine erstaunliche intraindividuelle Konstanz.
2. Untersuchungen von Leberkranken ergaben, daß der Funktionszustand der Leber keinen wesentlichen Einfluß auf die Ausscheidung von β-AIB im Urin hat.
3. Die Hälfte der untersuchten Patienten mit Hämochromatose scheidet größere Mengen dieser Aminosäure aus.
4. Der bei der Ahorn-Sirup-Krankheit auftretende Enzymdefekt (Ausfall der α-Ketosäureoxydasen) hat keinen Einfluß auf die Menge der eliminierten β-AIB.
Summary
1. β-AIB excretion varies greatly from individual to individual, whereas normal day to day differences in β-AIB excretion rates for any one person appear to remain constant.
2. Impaired liver function does not markedly alter urinary β-AIB excretion.
3. Half of our patients with hemochromatosis excrete large amounts of β-AIB.
4. Impaired activities of α-ketoacid-oxydases in maple syrup urine disease have no apparent effect on β-AIB excretion.
Abbreviations
- β-AIB:
-
